Description

Clamping structure, automotive sun-shading curtain and vehicle

Technical Field

The utility model relates to a clamping structure, a vehicle sunshade curtain with the clamping structure and a vehicle.

Background

When detachably assembling the related components, a clamping structure is generally used, and the structural complexity of the existing clamping structure is increased due to over consideration of firmness. In addition, for example, in a large bus, a light cloth curtain is generally used for shading the sun, and the cloth curtain is likely to float when air flows in the bus, which causes inconvenience to passengers. On the other hand, in passenger cars, undetachable shades are generally used, which limits the sharing of shades between individual windows.

Detailed Description

It is easily understood that according to the technical solution of the present invention, a person skilled in the art can propose various alternative structural modes and implementation modes without changing the essential spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.

Fig. 1 shows a clamping arrangement 1 according to the utility model, which has a base body 11 which is designed essentially flat or thickened at points which are subjected to high forces. A cutout 12 is provided in the base body 11, which cutout is not closed but is accessible from the outside, i.e. the object to be fastened can be inserted from the outside through the base body 11 into the cutout 12. As shown in fig. 1, the cutout 12 has a rectangular cross section and comprises a bottom side 121 and two mutually opposite end sides 122, which form a space that is open to the outside. The base body 11 can be produced by injection molding and, when the snap-in connection is to be fixed, it can be fixed by means of threaded fasteners by means of threaded bores 13 provided in the base body 11.

On the two opposite end sides 122, stops 14 are arranged, which are aligned with one another, said stops 14 being elastically deformable or movable in a certain direction by means of a certain external force in order to release the insertion path when an object to be fixed is inserted and to block said insertion path in the assembled state and to stop and support said object at said insertion path. More precisely, the stop 14 can be moved between an initial position, in which the stop 14 forms a receiving space with a supporting effect together with the cutout (i.e. its bottom side 121 and end side 122) in order to prevent the object from falling out of the cutout 12, and a final position, in which, on the other hand, there is sufficient space for the above-mentioned object to pass through.

The stop 14 can comprise a spring 141 and a projection 142 which are fixedly connected to one another and which are together fixed at the end side 122 of the cutout by means of the spring 141. In addition, bores 15 for receiving and fixing the stop 14 are provided on the end sides 122 of the two cutouts, from which bores the projections 142 project in the initial position in order to be able to support and stop the object received therein. The boss 142 is moved between the initial position and the final position in the longitudinal direction of the bore 15 (in the left-right direction in fig. 1) by the spring force. During assembly, the object is manually pushed into the cutout 12 against the spring force, so that it finally comes to rest at the end of the stop 14, and during disassembly, the object contained therein only has to be manually pulled out of it directly, for example downwards, which simplifies the mounting and dismounting process to a certain extent while satisfying the requirements of bearing fixation.

Optionally, in order to protect the object to be fixed from damage during the movement in and out, a rubber material, for example, is provided or wrapped at the end of the boss 142.

Optionally, a recess 123 is also provided at the bottom side 121 of the cutout, which recess, when form-fitting with the above-mentioned object, prevents the object from twisting therein, as will be explained in further detail below.

In addition, fig. 2 schematically shows a detachable vehicle sunshade 2 according to the present invention, comprising a roll-up mechanism 21, a curtain 22 and a pull rod 23. The winding-up mechanism 21 comprises a retractor 211, for example a spring retractor, and a rotary shaft 212, and a hollow-tube-shaped housing 213 for covering the rotary shaft, the curtain 22 being able to be wound up on the rotary shaft 212 by means of the retractor 211 and being accommodated in the housing 213. The retractor 211 is connected to the rotary shaft 212 so as to be able to transmit rotary motion, and the retractor 211 and the bearing 214 are respectively snapped into the housing 213 on both sides. The pull rod 23 is connected to the end of the curtain 22, by means of which the curtain can be pulled out manually through a slit (not shown) in the housing.

When the vehicle sun visor is assembled, its housing 213 is fixed to the roof by means of the above-mentioned snap-in connection, for example by means of a screw fastening to the roof sheet metal 3 and optionally further covered by the roof trim 4 (see fig. 4 and 5), which enables a concealed assembly of the vehicle sun visor and to a certain extent improves the use of the vehicle interior. In the assembled state, the housing 213 is supported at the stop 14 and is accommodated in the above-mentioned accommodation space, see fig. 3.

Optionally, a protrusion matching the shape of the groove 123 of the snap structure is provided on the outer circumferential surface of the housing 213 (see fig. 3). In the assembled state, it is received in the recess, thereby preventing the housing 1213 from twisting therein when the curtain 22 is pulled.

Alternatively, the sunshade for a vehicle according to the present invention has a separate hook (not shown) which can be disposed on the lower trim of the window, and accordingly, a bore 231 is provided on the draw bar 23 for hooking on the hook to further fix the curtain without a locking function.

When the sun-shading curtain is assembled, the sun-shading curtain is manually pushed upwards into the accommodating space of the clamping structure against the spring force, and when the sun-shading curtain is disassembled, the sun-shading curtain can be separated from the accommodating space only by manually pulling the sun-shading curtain downwards, so that the assembling and disassembling processes of the automobile sun-shading curtain are simplified, and the exchange of the sun-shading curtains among all windows can be realized.

The utility model also comprises a vehicle, to the or each window of which one or more vehicle blinds according to one or more of the embodiments described above are assigned, which therefore have the technical features and the technical effects corresponding to the above description and therefore are not described in detail in this context.

It should be noted that the size of the sunshade can be configured to be small for a targeted shading of the sun. For example, two vehicle shades are associated with a window, which can be pulled out simultaneously in the case of a large illumination range and one shade can be pulled out as required in the case of a small illumination range, as shown in fig. 4, two vehicle shades to be fastened by means of threaded fasteners (for example, one vehicle shade uses two threaded fasteners) being present on each side of the sheet metal roof. This alleviates the problem of the sunshade covering the line of sight of the driver or passenger to some extent.

It should be understood that all of the above embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon studying the above disclosure, are intended to be within the scope of the utility model.
